Schedule management of construction work is critical to completing construction projects within a given period of time. Many efforts have been made and multiple tools have been developed to support the management of construction projects using smart devices such as smartphones and tablet PCs. This study proposed a method for managing construction schedules via a smart device using Flash. The interactive and graphic properties of Flash enable the development of an app that can allow a field manager to manage schedules easily and efficiently. A prototype was implemented using Adobe Flex Builder, and a sample network was applied in a smartphone. It is convenient for a construction manager to manage construction schedules using the tool because Flash controls graphic components easily. In further studies, network diagrams such as CPM (Critical Path Method) should be developed and applied to the app.

As development of information technology, companies stress the need of knowledge management. Companies construct ERP system including knowledge management. But, it is not easy to formalize knowledge in organization. They experience that constructing information system help knowledge management. Now, we focus on engineering knowledge. Because engineering data contains experts' experience and know-how in its own, engineering knowledge is a treasure house of knowledge. Korean shipyards are leader of world shipbuilding industry. They have accumulated a store of knowledges and data. But, they don't have data minning tool to utilize accumulated data. This paper treats development of data minning tools for the utilization of shipbuilding knowledge based on genetic programming (GP).

Arrival management is a tool which provides efficient flow of traffic and reduces ATC workload by determining aircraft's sequence and schedules while they are in cruise phase. As a decision support tool, arrival management should advise on air traffic control service based on the understanding of human factor of its user, air traffic controller. This paper proposed a prediction model for air traffic controller sequencing strategy by analyzing the historical trajectory data. Statistical analysis is used to find how air traffic controller decides the sequence of aircraft based on the speed difference and the airspace entering time difference of aircraft. Logistic regression was applied for the proposed model and its performance was demonstrated through the comparison of the real operational data.

Post-Genome 시대의 Biotechnology(BT) 산업에 세계적으로 관심과 투자가 증가하고 있다. BT 산업은 기술 및 지식 집약적 특성상 R&D 활동이 중요하기에 BT 연구실의 실험 생산성 증가에 대한 연구가 필요하다. 이와 관련하여 연구실 지식경영과 지식경영시스템활용에 관한 연구가 활발히 진행되고 있다. 하지만 그 초점이 연구 지식들의 조직화, 체계화 및 검색기능 등의 원활한 지식 공급 시스템 구축에 있기에 효율적이고 효과적인 지식 생성 방안을 제시해 주지 못하고 있다. 이에 본 연구는 실험실 내 데이터 처리 및 통합 관리 역할을 해온 LIMS(Laboratory Information Management System)를 활용하여 실험 데이터들로부터 실험 디자인을 위한 효율적이고 효과적인 형식지(Explicit Knowledge)의 생성을 목적으로 하는 지식 생성 툴(Knowledge Creation Tool)을 설계하였다. 또한 상기 모델을 적용하여 실제 어떠한 형태로 지식이 생성되는지 A대학교 B유전자 연구실의 실험 데이터로 실증 분석해 보았다.

In complex industrial world, many companies make every effort to analyze their competition capability through various performance evaluation tools to cope with rapidly changing business environment. Among evaluation tools the balanced scorecard (BSC), put forward by Kaplan and Norton in 1992, is a strategic performance management tool for measuring whether the smaller-scale operational activities of a company are aligned with its larger-scale objectives in terms of vision and strategy. The BSC tool offers a comparative advantage over others to evaluate the objective achievement of a company by linking its strategic objectives with operational KPI. In this paper, we introduce a case that the BSC performance evaluation system was implemented based on product data management and applied it to the business process. Specially, we shows a implementation procedure to derive discipline-specific topics and key performance metrics.

The competition between companies for prior occupation of the market is becoming fierce. In this highly competitive situation, it is important for companies to differentiate themselves if they are going to have a chance at success. And the competition to create the best solution method possible is higher than ever. Increased competition is forcing companies to lower costs and improve efficiency. A supply chain management(SCM) has become one of the most important solution methods of competitive advantage. This study has developed a simulator for the supply chain network problem. The simulator is designed to simulate the conditions of an actual supply chain network considering uncertainties. The simulator developed using commercial simulation tool ARENA and the results of computational experiments for a simple example were given and discussed to validate the developed simulator. Further research is needed, but using the simulator could become a useful tool for decision making in the supply chain network area.

This study analyzes weather derivatives as an alternative risk management tool to stabilize farm revenue to complement the existing crop insurance program which suffers from asymmetric information problems such as adverse selection, moral hazard, and verifiability. We estimated apple yield functions to observe the relationship between yields and weather indices such as temperature and precipitation. Based on the estimated yield functions we designed weather futures and options products underlying temperature and precipitation, and calculated the prices of futures and options by two different approaches, historical distribution and Monte Carlo simulation. We found that weather futures and options stabilize farm revenue based on the estimated four risk indicators: Coefficient of Variation, Value at Risk, Certainty Equivalence, and Risk Premium. As a result, weather derivatives could be considered as a potential farm risk management tool through studying more in legal and institutional strategies and developing various derivatives products.

Research sponsored by the Korean Government investigated the establishment of a risk management process by Korean contractors involved with plant projects in the Middle East. This research effort builds upon the work completed by the Construction Industry Institute (CII), called the International Project Risk Assessment (IPRA) tool and method, and also explored how CII's Project Definition Rating Index (PDRI) could be incorporated to improve project planning by addressing risks and scope development issues. Specific findings and recommendations were developed including the creation of the Contractor Critical Areas of Concern (CCAC) risk screening tool for Korean contractors pursuing Middle East oil and gas projects.

The collection management paradigm has drastically changed since the emergence of collection management activities on the internet. Due to the technological development of web, web has become the newly open field as a useful tool to facilitate collection management transactions. The purpose of this study is, by evaluating web sites of the university library’s collection management in United States, to construct the contents of collection management web site. To fulfill the purpose, 6 categories for the contents of the collection management web site are suggested. The result of this study can be used as the basic data for researching of collection management web site. Web site is playing a role of stepping up its activities and informing useful information on its selection tool and collection development policy.

I/O processing speed of relatively sluggish storage devices incurs overall performance degradation in computer systems. As a solution to improve the situation, SAN(Storage Area Network) has been proposed. In order to utilize a SAN system more effectively, where storage devices are directly connected with a high speed network such as Fibre Channel, a proper management tool is needed. In this paper, we present a design and implementation of a performance monitoring and configuration management tool for the SANtopia system which supports global file sharing in the SAN environment The developed tool is to monitor the performance of the Linux hosts composing the SANtopia system and to manage the configuration of the hosts and storage devices. It also supports GUI(Graphic User Interface) environment using the JAVA programming language.
